November this year, DH turns 30!

I have zero gift ideas for him. He's into cars and tools - he'd like a drop saw lol - but I want to get him something special. The problem is he doesn't wear jewellery, not even a watch or wedding ring, because of his job. So I can't get him something like that engraved.

We'll have a very new baby at that stage (edd 23/10, DH birthday 16/11) so I'm thinking I should start thinking about it now.

Any ideas to throw at me?
